WATER-HEATER.

Specification of Letters Patent.

Patented May 28, 1907.

To all whom, it may concern:

Be it known that we, ALBERT OLESON, WILLIAM A. WILLIAMS, and (Immune O. WILLIAMS, all of whom are citizens of the United States, residin at Toledo, county of Lucas, State of Ohiofiiave invented certain new and useful Im rovements in Water- Heaters; and we dec are the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference bein had to the accompanying drawings, which orm a part of this specification.

This invention relates to water heaters, and has for its object an im roved means whereby the contents of an or 'na upright domestic heater may be quickly an economically heated by means of an attachment which occupies but little space, and is equally adapted to use either gas or kerosene.

In the drawin s:Fi ure 1, is a vertical sectional view 0 a boi er of'this type, in which our invention is installed. Fig. 2, is a vertical sectional view ofthe lower art of the boiler, and of a modified form of eatin chamber of the shape shown-in Fig. 1, an which is cast in one piece.

A, indicates an ordinary upright boiler with a cold water intake openingB, and a hot water outlet O. D is an outlet to which a mud valve may be attached. Through the center of the boiler extends a flue F, which may open either into the outer air or into a chimney or stove pipe, and which, at its lower end, communicates with a chamber R, which is of the shape of two truncated cones laced with their bases adjacent, so that the widest part ofthe chamber thus inclosed is approximately midway between the top and bottom of the chamber. The lowermost portion of the lower or inverted cone E joins the edges of the diaphragm H, which incloses a space which is in communication with the chamber formed by the two truncated cones, and from which similarly all water is at all times excluded. Extending throu h the bottom plate G of the boiler is a supp y pipe K through which the fuel used may be supplied to a burner L, which is just above the union of the diaphra m H and the walls E. When the burner is lig Ited, the only escape for the heat thus generated being u the flue F, the surrounding walls E J, and communicate this heat to the water on their outer faces. The inlet pipe B in Fig. 1 being located at a tion of the cffamber walls, furnishes t e cold water at a most desirable oint for heating, and this may be depended upon to rise and ive way to other water as soon as itis eated. The resilience of the material of the walls 'J, E, and H is such that the flue F can be screwed down as much or as little as desired to make a tight joint from its controllin nut N in the crown plate of the boiler. 11 Fig. 2 a slight variation in-the form of chamber shown in Fig. 1, is disclosed, the component walls M being cast in a si la piece, instead of riveted together, as J, and H in 1, the inlet pi e B opening at some point that is below t e greatest projection of the walls M, and there may be laced several pipes T leading from the ower or overhanging face P of the walls through to the upper faces Q, which facilitate the rise of the heated water from the lowermost part of the water chamber to the upper part of the boiler, without necessitating the passa e of all such Water past the projecti shoul ers of the heating chamber. In a the types, however, reliance is placed on the heating of the walls of the heating chamber because of the small capacity and the small amount of 'heat which the flue can carry away, rather than the direct impinging of the-flame u on the walls which separate the water,and eating chambers.

What we claim is 1. In a water heater, in combination with are very quickly heated and soon oint below the greatest rojeca vertically extending tank, provided with an inlet orifice near its lower end and with an outlet orifice near its upper end, a flue extending lengthwise thereof to a point external to its upper end, and wholly out of communication with the fluid containing part of the tank, a biconical chamber truncated at each end and connected at one end with the inner end of said flue, that portion of the chamber which is of greatest diameter being located above the inlet orifice, a diaphragmregistering with the lower end of the chamber, and, with the walls thereof, closing its interior from communication with the watercontaining portion of the tank, and a burner a tank provided with an inlet ning nearthe bottom portion and an out at opening.

near the top, ardiaphra m partially closing the lower end of the tan a burner communicating with an external source of fuel supply extending through the open central ortion of the diaphragm, a biconical cham er, whose greatest diameter is at its center portion about said burner and registering with its lower edge with the open portion of the diaphra m, its greatest diametrical portion being afiove said inlet opening, and a flue leading from the top of said chamber and passing through the tank tothe outer air at the top thereof, substantially as described.

3. In a water heater, in combination with a tank provided with an inlet opening near the bottom thereof,-a diaphragm, whose central portion is perforated, within the tank and spaced from one end thereof, a burner in communication with an external source of supply cngagingthrough the perforated central portion of said diaphragm, a biconical air chamber surrounding said burner and wholly out of communication with the water-containing portion of the tank, the lower edges of its walls being complementary to and connected with the centrally perforated edge of the diaphragm, and that portion of the chamber whose diameter is greatest beinlet and outlet pipes, a water tight chamber u in the bottom portion of said tank, and connecting at its upper end with said flue, and its top and bottom portions being of smaller diameter than the center portion, a plurality of conductor pipes extending through said chamber from apertures in the lower portion of the walls of said chamber to similar apertures in the upper surface of the walls of the chamber, and a burner within the chamber communicating with a source of fuel supply external thereto, substantially as described.

In testimony whereof, we sign this s'pecifipresence of two Witnesses.
